Een studie van Tucatinib of Placebo met Trastuzumab en Pertuzumab voor gemetastaseerde HER2+-borstkanker (HER2CLIMB-05)

4 september 2026 bijgewerkt door: Seagen, a wholly owned subsidiary of Pfizer

Een gerandomiseerde, dubbelblinde, fase 3-studie van tucatinib of placebo in combinatie met trastuzumab en pertuzumab als onderhoudstherapie voor gemetastaseerde HER2+-borstkanker (HER2CLIMB-05)

This study is being done to see if tucatinib works better than placebo when given with other drugs to treat participants with HER2-positive breast cancer. A placebo is a pill that looks the same as tucatinib but has no medicine in it. This study will also test what side effects happen when participants take this combination of drugs. A side effect is anything a drug does to the body besides treating your disease.

Participants will have cancer that has spread in the body near where it started (locally advanced) and cannot be removed (unresectable) or has spread through the body (metastatic).

In this study, all participants will get either tucatinib or placebo. Participants will be assigned randomly to a group. This is a blinded study, so patients and their doctors will not know which group a participant is in.

All participants will also get trastuzumab and pertuzumab. These are 2 drugs used to treat this type of cancer.

Maatregel Beschrijving
Tijdsspanne
Progression-Free Survival (PFS) as Assessed by Investigator Per Response Evaluation Criteria in Solid Tumors (RECIST) Version (v) 1.1
Tijdsspanne: From randomization until the first documentation of PD or death from any cause or censoring date, whichever occurred first (maximum treatment exposure was of 41.3 months)

PFS: time from randomization to the first documented disease progression (PD) (as assessed by investigator per RECIST 1.1) or death from any cause, whichever occurred first. PD: >=20% increase in sum of diameters of target lesions, taking as reference the smallest sum of diameter recorded since the treatment started or the appearance of 1 or more new lesions. Participants without documentation of PD/ death at the time of analysis, were censored at date of last tumor assessment with an overall response of complete response (CR), partial response (PR), stable disease (SD), non-CR/non-PD or no evidence of disease (NED). CR: disappearance of all target lesions; PR: >=30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum of diameters; SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum of diameter since the treatment started. Kaplan-Meier method was used for analysis.

From randomization until the first documentation of PD or death from any cause or censoring date, whichever occurred first (maximum treatment exposure was of 41.3 months)

Tijdsspanne
Overall Survival (OS)
Tijdsspanne: From the date of randomization until date of death or censoring date (approximately 66.7 months)

OS: time from randomization to death due to any cause. For a participant who would not known to have died by the end of study follow-up, observation of OS would be censored on the date the participant was last known to be alive (i.e., the date of last contact).

From the date of randomization until date of death or censoring date (approximately 66.7 months)
PFS as Assessed by Blinded Independent Central Review (BICR) Per RECIST v1.1
Tijdsspanne: From randomization until the first documentation of PD or death from any cause or censoring date, whichever occurred first (maximum treatment exposure was of 41.3 months)

PFS per BICR was defined as the time from the date of randomization to the documented disease progression assessed by BICR according to RECIST v1.1 or death from any cause, whichever occurred first. As per RECIST v1.1, PD: >=20% increase in sum of diameter of target lesions, taking as reference the smallest sum of diameters recorded since treatment started or appearance of 1 or more new lesions, unequivocal progression of existing non-target lesions. Participants without documentation of PD/ death were censored at date of last tumor assessment with an overall response of CR, PR, SD, non-CR/non-PD or NED. CR: disappearance of all target lesions; PR: >=30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum of diameters; SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum of diameter since the treatment started. Kaplan-Meier method was used for analysis.

From randomization until the first documentation of PD or death from any cause or censoring date, whichever occurred first (maximum treatment exposure was of 41.3 months)
Time to Deterioration (TTD) of Health-Related Quality of Life (HRQoL)
Tijdsspanne: Approximately 66.7 months

Time to deterioration of HRQoL was defined as time to 10-point decrease in the global health status/QoL scale of the European Organization for Research and Treatment of Cancer (EORTC) quality of life questionnaire (QLQ-C30). EORTC QLQ-C30 is 30 item questionnaires composed of 5 multi-item functional domains (physical, role, cognitive, emotional, and social), 3 symptom scales (fatigue, pain, nausea, and vomiting) and 6 single items for symptoms (shortness of breath, loss of appetite, sleep disturbance, constipation, diarrhea and financial impact of the disease), 2 global items (health, overall QoL). Higher functional/global QoL score = better functioning and higher symptom score = greater degree of symptoms.

Tijdsspanne: From randomization until the first documentation of PD or death from any cause or censoring date, whichever occurred first (maximum treatment exposure was of 41.3 months)

CNS-PFS was defined as the time from randomization to investigator assessed disease progression in brain according to RECIST v1.1, or death from any cause, whichever occurred first. As per RECIST v1.1, PD: >= 20% increase in sum of diameter of target lesions, taking as reference the smallest sum of diameters recorded since the treatment started or appearance of 1 or more new lesions, unequivocal progression of existing non-target lesions. Participants without documentation of PD/ death at the time of analysis were censored at date of last tumor assessment with an overall response of CR, PR, SD, non-CR/non-PD or NED. CR: disappearance of all target lesions; PR: >=30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum of diameters; SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum of diameter since the treatment started. Kaplan-Meier method was used for analysis.

From randomization until the first documentation of PD or death from any cause or censoring date, whichever occurred first (maximum treatment exposure was of 41.3 months)
Number of Participants With Treatment Emergent Adverse Events (TEAEs)
Tijdsspanne: From first dose of study treatment (Day 1) up to 30 days after the last dose of study treatment (maximum up to 42.3 months)

An adverse event (AE) was any untoward medical occurrence in a clinical investigational participant administered a medicinal product and which did not necessarily had a causal relationship with this treatment. TEAEs were defined as events that were new or worsened on or after receiving the first dose of study treatment and up through 30 days after the last dose of study treatment. AEs included both Serious AE (SAEs) and all other AEs. An AE should be classified as a serious SAE if it meets one of the following criteria: fatal, life threatening, requires or prolongs hospitalization, disabling/ incapacitating, congenital anomaly or birth defect, medically significant.

From first dose of study treatment (Day 1) up to 30 days after the last dose of study treatment (maximum up to 42.3 months)
Number of Participants With Treatment Emergent Laboratory Abnormalities
Tijdsspanne: From first dose of study treatment (Day 1) up to 30 days after the last dose of study treatment (maximum up to 66.7 months)

TEAEs were defined as events that were new or worsened on or after receiving the first dose of study treatment and up through 30 days after the last dose of study treatment. Treatment emergent laboratory abnormalities include: hematology (hemoglobin decreased, hemoglobin increased, leukocytes decreased, neutrophils decreased, platelets decreased); chemistry (alanine aminotransferase increased, alkaline phosphatase increased, aspartate aminotransferase increased, creatinine increased, potassium decreased, potassium increased, sodium decreased, sodium increased, total bilirubin increased).

From first dose of study treatment (Day 1) up to 30 days after the last dose of study treatment (maximum up to 66.7 months)
Number of Participants With TEAEs Leading to Dose Discontinuations
Tijdsspanne: From first dose of study treatment (Day 1) up to 30 days after the last dose of study treatment (maximum up to 66.7 months)

TEAEs were defined as events that were new or worsened on or after receiving the first dose of study treatment and up through 30 days after the last dose of study treatment. In this outcome measure, number of participants with TEAEs leading to dose discontinuations with study treatment will be reported.

From first dose of study treatment (Day 1) up to 30 days after the last dose of study treatment (maximum up to 66.7 months)
Number of Participants With TEAEs Leading to Dose Hold
Tijdsspanne: From first dose of study treatment (Day 1) up to 30 days after the last dose of study treatment (maximum up to 66.7 months)

TEAEs were defined as events that were new or worsened on or after receiving the first dose of study treatment and up through 30 days after the last dose of study treatment. In this outcome measure, number of participants with TEAEs leading to dose hold with study treatment will be reported. Dose hold requirements are defined per protocol.

From first dose of study treatment (Day 1) up to 30 days after the last dose of study treatment (maximum up to 66.7 months)
Number of Participants With TEAEs Leading to Dose Reductions
Tijdsspanne: From first dose of study treatment (Day 1) up to 30 days after the last dose of study treatment (maximum up to 66.7 months)

TEAEs were defined as events that were new or worsened on or after receiving the first dose of study treatment and up through 30 days after the last dose of study treatment. In this outcome measure, number of participants with TEAEs leading to dose reductions with tucatinib, trastuzumab and pertuzumab are reported. Dose reduction requirements are defined per protocol.

From first dose of study treatment (Day 1) up to 30 days after the last dose of study treatment (maximum up to 66.7 months)
Trough Concentration (Ctrough) of Tucatinib
Tijdsspanne: Pre-dose on Day 1 of Cycles 2, 3, 4, 5 and 6

Concentration at Trough was defined as predose/trough concentration observed directly from data.

Pre-dose on Day 1 of Cycles 2, 3, 4, 5 and 6
